Ok, so let's see if I have the times figured out a tiny bit better....
This "Copenhagening" takes place sometime in 1904, and some interesting things are also going on in history around the same time.
Anglo-Japanese Alliance
Russo-Japanese War
Entente Cordiale
So, the Anglo-Japanese Alliance was a British attempt aimed at Russia, to have Japan curtail Russian ambitions in asia, first signed on Jan 30th, 1902. This does not make the Czar well disposed towards merry old England.
Russo-Japanese War, which starts on 9 Feb, 1904. Which just happens to begin with a Japanese surprise attack on the Russian Pacific fleet, based at port Arthur.
The Entente Cordiale, signed in April, 1904...Just 2 months after the Czar's fleet is hard hit...
And then, the RN decides on a surprise attack upon the German navy.
Yep, the UK/France can definitely count on the Czar's support and friendship in this ATL.
So, this gives us quite a different picture of the situation in this alternate timeline from our own, and WWI is not going to start 10 years later, but likely the day the UK decides to make their own surprise attack. Germany sees the Russians attacked by a British ally (Japan), who happened to be allied to Britain's newest friend (France), and then sees her own fleet attacked by the British. Hmmmm. Russia sees Germany, ruled by the Czar's cousin, Willy, getting the same treatment as he himself has just received, and so NO,
there will be no fighting between Russia and Germany. The only two significant remaining questions I see are dealing with France and the United States.
France, is she part of the happy
"Imperialist World War" that the UK is behind? France, and not Britain, shares a land boarder with Germany, did the UK tell France about the planned attack, so the french could mobilize their army (goodbye element of surprise), or did the UK leave their ally hanging out in the wind?
The United States, up to now enjoying her isolationist existence apart from the
Spanish-American War now sees a very disturbing pattern developing, what with not one, but two wars of aggression started off by surprise attacks upon the naval forces of Russia and Germany, and both these attacks by island nations that are dependant upon imported goods not just to feed their industry, but their populations as well. Global crushing of potential naval rivals? The USA and Japan are definitely already looking at each other as rivals for trade in Asia (The Germans, with a loss of some of their fleet, and their involvement in a major land war in Europe unless the French drop the alliance with the UK like the proverbial hot potato, not so much anymore), and by the British acting in such a fashion, who knows what is to come next?
So, some interesting variations for us to play with here. Are the attacks confined to just the two outlined, or are/is the strategy more global, IE, are the French in on it and readying themselves for war with Germany? Is the USA left out of the planning, and just assumed to be up for going along with the new world order? Or are there other plans, to account for the USA's own fleet?
Now where so we go from here...?
